TO ALL WHOM IT lHAY, CONOERN:

Be it known that I, JOHN B. OSIER, of Ogdensbnrg, in the county of S'tfLawrence, and State of Newv York, have inented a new and improved Mode of Cutting Sheet Iron and Tin; and I do hereby declare that the following is a. full and exact des'criptic'ur thereof, referenceibeing had to the accompanying drawings, and to'the .letters of reference marked thereon. .I v i y I i TheV nature of my invention consistsin providing tufo rectangular frames A A, attached to each other at B B, one with an inclined plane on the top, for the better facilitating the knives in cutting. On one frame are attached tivo perpendicularl guides, Chat the Acorners of frame, at oneend, and across is attached a cross-bar, thatrises and falls on the guides; and on said bai` are bolted knives with the edge being angular; and, in pressing the foot upon the treadle I, the knives are forced down-wards; and, in passing by the knife on ithecther frame, at E, the edge being straight, the `knife commences vto cut at each outside edge ofthe sheet to beeut, and finishes at the middle ofthe knife.

To enable others skilled in the art to .make and use my invention, I will proceed to describe its construction and operation. n

- I construct two rectangular frames A A, of sutlicient size and Width, support-ed on legs at the requisite height, and attached `to each other at B B. On the top of one frame is an inclined top, and on the other is a. level top of equal height. On one of the level tops, at the corners, are attached two-perpendicular guides, C C, on whichis attached a cross-bar, D, on-which are bolted knives,` the edge being angular, Vthe edge at each end being lower, and in itsdownward motion the outside of the sheet commences t-o c ut irst,'and finishes on the middle of' theknife. On the end of the 'fra-me with .the inclined plane on top, is attachedva. cross-bar, E. At each end of barlare attached three bolts, to move the knife at its proper distance, so as to let one` knife pass close to eachother in.its motion. On the bar E is attached a knife, with the edge straight. On the top of the inclined plane is sliding guide, F, and at each side-ofthe top are marked the feet and inches, so as to set the guide at any desirable distance, thus enabling the operator to cut any desired width. On the top of the perpendicular giuideslis attached a cross-bar, G, on the top of 'which is attached a spring, H, and throughthe spring in the middle, is attached a. rod that passes through and attached to cross-bar D,.and through the cross.- bar G, thusV keeping the cross-bari) held up at sufficient height toallow the sheet iron ortin to pass through from one .frame to the other on the top of the inclined plane-to be cut. I'is a treadle,l attached under frame A, and J is a cross-bar, attached at each endhy-rods K K, and Yattached to cross-har D, andlpasses between each frame at -thcmiddle, and attached. to-treadle I by a rod. a The operator, in pressing his foot upon the treadle I, is `enabled to force doivn the cross-baril), and in passing the cross-bur E, with the knifcnttached, is enabled to cut sheetiron and tin, ns desired.

What I claim as my improvement, and desire to secure by Letters Patent, is Y The construction and arrangement of the frames l./*tA'with the perpendicular guides C @angular knife, and cross-bars D and E, with the spring H, and sliding guide F, and treudle I, all armvged'llld COl'nOict-ed for the purpose set forth.- v

J. B. OSIER.
